Chapter 21: Process Costing

Chapter Introduction

Marie has been learning about job order costing for her catering services, but she's curious about a different situation. "What about businesses that make the same thing over and over?" she asks Monsieur Schneider. "Like a bakery that makes hundreds of identical loaves of bread every day, or a company that bottles the same beverage continuously. How do they track costs?"

Monsieur Schneider explains that these businesses use process costing. "Process costing is used when products are identical or very similar and produced in large quantities," he says. "Instead of tracking costs for each individual unit, process costing accumulates costs by process or department and calculates an average cost per unit. This is much more efficient for mass production."

Process costing is a costing system used when products are homogeneous (identical or very similar) and produced in large quantities through continuous processes. Costs are accumulated by process or department, and an average cost per unit is calculated.

In Luxembourg, process costing is important for manufacturing SMEs because:

• Some SMEs produce identical products in large quantities
• Food processing businesses use process costing
• Beverage production uses process costing
• Understanding process costs helps with pricing and efficiency
• Process costing supports cost control in mass production

This chapter teaches you how process costing works, how to calculate equivalent units, how to allocate costs to completed and in-process units, and how to prepare process cost reports. You'll also learn how to apply process costing in Luxembourg manufacturing SMEs.

By the end of this chapter, you'll understand how to use process costing for businesses that produce identical products—just like you'll see in Luxembourg food processing and manufacturing companies.

Why It Matters

Process costing is essential for businesses that produce identical products in large quantities because:

• Efficient Cost Tracking: More efficient than tracking each individual unit
• Average Cost Calculation: Provides average cost per unit for identical products
• Process Improvement: Helps identify cost issues in specific processes
• Pricing Decisions: Supports pricing for mass-produced items
• Cost Control: Enables monitoring of process costs

Luxembourg-Specific Importance:

• Some Luxembourg SMEs use process costing
• Food processing businesses need process costing
• Beverage production uses process costing
• Understanding process costs supports competitive pricing
• Process efficiency is important for profitability

Understanding process costing helps you:

• Track costs for mass production
• Calculate average unit costs
• Identify process inefficiencies
• Make pricing decisions
• Control production costs

Learning Objectives

By the end of this chapter, you should be able to:

1. Compare and contrast job order costing and process costing

3. Explain and compute equivalent units and total cost of production in an initial processing stage
4. Explain and compute equivalent units and total cost of production in a subsequent processing stage
5. Prepare journal entries for a process costing system
6. Understand Luxembourg manufacturing SME process costing applications
